Patent DE-19642438-A1 (DE)
Title: Sealing machine for packages for free-flowing powders
Inventor: KRAUSE GUENTER
IPC: B65B7/02
Filed: 1996-10-15
Abstract: The packaging machine has the filled rectangular packs (5) laid flat on a conveyor belt. They are transferred onto support grids (10) which are supported at the four corners by two belt drives to raise the grids vertically while maintaining the horizontal position. The valves (7) attached to the bottom edge of each pack are moved vertically between two sealing flanges (19,20) for heat sealing to secure the packs. The valves are held between two belt drives while being moved vertically. This pinches them shut while residual material is blown out of the open ends of the valves by compressed air jets. Sealing follows while the valves are still held between the belt drives. The final process folds the valves flat under the bottom of each pack before the packs are moved onto an output conveyor (4).

Abstract: A radiator valve is disclosed, having a housing (2, 3), a closing element (6), which comprises a head part (18) and a body (19), and a tappet (25) which is guided through a stuffing box (28) and lies adjacent to the head part (18) which projects into a housing bore (24), into which also the tappet (25) projects. It is desirable that such a valve can on the one hand be manufactured cost-efficiently, but on the other hand preserves the seal when the stuffing box (26) is replaced. For that purpose the head part (18) widens conically beyond the diameter of the housing bore (24). <IMAGE>

Patent DE-19711194-A1 (DE)
Title: Pipe line leak detection method
Inventor: SKLARZ HORST
IPC: F17D5/02
Filed: 1997-03-19
Abstract: The method involves placing sealing bags (B1,B2) at two points in a sewer pipe and inflating them with compressed air to form a seal against the inner wall of the pipe. The bags are spaced apart at a specific distance to form a test chamber. They are charged with air until a reference pressure is reached and a pressure sensor (DM) signals a control unit of this.  If the pressure falls below a specific value the bags are replenished. The volume of test medium required for filling the test chamber is determined by computer. Water or air is then introduced into the teat chamber through pipework passing through one bag until a pressure sensor (DM) indicates that the computed quantity has been reached and, after a waiting period set by the computer, the test chamber is if required topped up. The measurement graph is recorded

Patent DE-19733322-A1 (DE)
Inventor: KORTE VOLKER
IPC: F02D13/04
Filed: 1997-08-01
Abstract: The invention relates to a valve control system for an internal combustion engine which can be switched into a drive or brake mode, comprising both a brake-camshaft and a main camshaft acting upon the exhaust valves. The aim of the invention is to adapt engine braking power to various requirements. To achieve this the two camshafts are arranged in such a way as to enable phase displacement in relation to each other using a phase adjustment mechanism. When only a low braking power is required, decompression occurs clearly before or only after top dead centre so that part of the compression work does not need to be conducted in the first case and is recovered by means of expansion in the second case.

Inventor: REITER FERDINAND
IPC: F02M51/06
Filed: 1997-09-11
Abstract: The inventive electromagnetically operated valve is characterised in that an axially moveable valve needle (6) consisting of an armature (12), a valve closing body (13) and a connecting part (14) connecting these two parts is provided. The tubular connecting part (14) has a longitudinal slit (51) whose opening width is narrower at the end (56) facing towards the valve closing body (13) than across the rest of its axial extension due to flaring in the original sheet part.

Inventor: OTTER WALTER
IPC: H01F7/16
Filed: 1998-01-30
Abstract: The aim of the invention is to configure a fast-acting hydraulic valve, so that the time which passes between the signal being given from outside and the valve body (35) completing its switching movement from the first switch position to the second switch position is very short. To this end, a second electromagnet (40) which acts on the valve body (35) so that it switches from the second switch position to the first is provided. When the second electromagnet (40) is activated and the valve body (35) takes up the first switch position, it retains said first switch position even if the first electromagnet (14) is activated. In order to switch the valve body (35) from the first switch position to the second switch position, the second electromagnet (40) is deactivated whilst the first electromagnet (14) remains activated.
